A black eye is bruising and swelling around your eye, usually caused by a blow to the area, such as a punch or fall. It should get better within 2 to 3 weeks.
gently hold an ice pack (or a bag of frozen peas wrapped in a cloth) to the area around your eye for about 10 to 20 minutes at a time, and repeat regularly during the first 1 to 2 days
take painkillers such as paracetamol or ibuprofen for any pain
after the first 2 days, gently apply a warm (not hot) heat pack or cloth to the area around your eye regularly during the day
do not take aspirin, unless prescribed by a doctor, as this can make the bruising worse
do not press or rub the area around your eye
do not put ice directly on your skin
